AI Technical Summary

Benefits of technology

"The present invention is about a composition that can be used to improve the safety of plants by using an auxiliin, an auxiliin precursor, an auxiliin metabolite, or a derivative of these compounds. The composition can be applied to plants to protect them from damage caused by agrochemicals, such as herbicides, without reducing their effectiveness. The composition can be applied as a mixture with the agrochemical or before or after it. The invention also includes a method for improving plant safety by applying the composition to the plants or their environs or plant propagation material. The composition can be applied as a separate kit for use in crops. Overall, the invention provides a way to protect plants from damage caused by agrochemicals while maintaining their effectiveness."

Problems solved by technology

For example, such chemicals may damage the crops to which they are applied, as well as the species to which they are targeted.
This is a particular problem in the field of non-selective fertilisers.
These fertilisers, fungicides, pesticides, insecticides and herbicides may also be hazardous.
Other compositions applied to plants such as plant growth regulators, chemical thinners and abscission delay agents also often have negative effects on crops and may also be hazardous.

Safening of Fertilisers

[0139]Safening systems were applied to crops of winter barley, winter wheat and lettuce treated with various fertilizers (Potassium Phosphite, potassium phosphite+ammonium thiosulphate, general NPK fertiliser). The safening system and the fertilizer were applied either simultaneously or sequentially.

Winter Barley: cv Saffron, sown 27 May 2008, at four / five seeds per 9 cm pot, sown in standard multi-purpose compost of pH 6.5. Date of spraying: 23 July; Dates of measurement / scoring: 30 July, 14 August, 22 August. Sprayed: mid-tillering phase (GS23).

Winter Wheat: cv Limerick, sown 4 Jun. 2008, at four / five seeds per 9 cm pot, sown in standard multi-purpose compost of pH 6.5. Date of spraying: 23 July; Dates of measurement / scoring: 30 July, 14 August, 23 August. Sprayed: mid-tillering phase (GS23).

Lettuce: cv Set, sown 10 Jul. 2008, at one seed per pot, in John Innes No 1 compost. Date of spraying: 30 July; Dates of measurement: 7 August, 14 August, 28 August. Spr...

Safening of Fungicides

[0145]Safening systems were applied to crops of winter barley, winter wheat and maize treated with various fungicides (Prochloraz, Flutriafol, Fenpropidin). The safening system and the fungicide were applied to the crops either simultaneously or sequentially, either as foliar applications or as a seed treatment.

Winter Barley: cv Saffron, sown 27 May 2008, at four / five seeds per 9 cm pot, sown in standard multi-purpose compost of pH 6.5. Date of spraying: 23 July; Dates of measurement / scoring: 30 July, 14 August, 22 August. Sprayed: mid-tillering phase (GS23).

Winter Wheat: cv Limerick, sown 4 Jun. 2008, at four / five seeds per 9 cm pot, sown in standard multi-purpose compost of pH 6.5. Date of spraying: 23 July; Dates of measurement / scoring: 30 July, 14 August, 23 August. Sprayed: mid-tillering phase (GS23).

Maize: cv Sundance, sown 25 May 2008, at 10 seeds per 25 cm pot, in John Innes No 1 compost. Date of measurement / assessment: 15 June. Seed treatment trial. Ra...

Safening of Herbicides

[0153]Safening systems were applied to crops of oilseed rape and winter treated with various herbicides (Bifenox (with insecticide), Carbetamide, Propaquizafop, Chlorotoluron, Isoproturon, Flumioxazin). The safening system and the herbicide were applied to the crops either simultaneously or sequentially.

Oilseed rape: cv Excalibur, sown 26 Apr. 2008, at two seeds per 9 cm pot, sown in normal pH multi-purpose compost. Date of spraying: 6 June; Dates of measurement / scoring: 13 June, 20 June, 5 July.

Winter wheat: cv Alchemy, sown 23 Apr. 2008, at seven seeds per 9 cm pot, sown in normal pH multi-purpose compost. Date of spraying: 24 May; Dates of measurement / scoring: 31 May, 7 June, 21 June.

SAF: at least one from class (f) each at <3 g / l, plus at least one from class (c).

Abstract

A compound selected from a composition comprising an auxin, an auxin precursor, an auxin metabolite or a derivative of said auxin, auxin precursor or auxin metabolite and acetaminophen or a derivative thereof for use as a plant safener.

Description

FIELD OF THE INVENTION[0001]This invention relates to a method and composition for improving crop safety by treating plants with, particularly but not exclusively, a composition comprising an auxin, an auxin precursor, an auxin metabolite or a derivative of said auxin, auxin precursor or auxin metabolite and acetaminophen or a derivative thereof.BACKGROUND OF THE INVENTION[0002]Chemical fertilisers, fungicides, insecticides and herbicides are applied to plants in order to promote growth and reduce or destroy unwanted fungi, pests, weeds and other unwanted species. This is of particular importance in the field of commercial farming, where obtaining the maximum yield is of the utmost importance.[0003]Chemical fertilisers, fungicides, pesticides, insecticides and herbicides available to-date often have negative effects on crops, as well as the positive effect of reducing unwanted species and promoting growth. For example, such chemicals may damage the crops to which they are applied, a...
